Recently, I've been unable to access my F: drive. When I double click on the drive I get en error that says "Application Not Found". I can, however right click on the drive and open it that way, it's just extremely annoying. It doesn't matter what device is set as the F: drive, be it a UBS drive, a virtual drive, or a CD/DVD drive, it gives me the same error. At first I thought maybe there was something wrong with my USB drive, but if I use the same USB drive as E:, G:, H: etc. it works perfectly fine. The problem seems to lie specifically with F: drive itself. I've run all my virus scans (Norton and Malwarebytes) as well as PC Tools Registry Mechanic and found nothing. I even restored my system to about a week ago with no results. Any help would be appreciated.
